Hydraulic circuit for controlling user of work apparatus has pump supplying user with pressure medium via feed conduit with back flow conduit feeding back to tank

摘要

In the feed conduit and the back flow conduit (14,16) is connected a pre-controlled pressure limiting valve (4,4'), via which when a limit pressure is exceeded the pressure medium can be conducted to a low pressure area. A brake pressure indicator conduit (34) is incorporated via which a pre-control valve body of the pressure limiting valve is fed indirectly or directly with a pre-control load pressure corresponding to the load of the work apparatus (8).
